MECHANICAL MOVEMENT.

JPEOIFIGATION forming part of Letters Patent No. 459,208, datedSeptember 8, 1891.

Application filed January 12. 1891. Serial No. 377,475. (No model-l Toall whom it may concern.-

Be it known that I, GEORGE O. SCHNELLER, of Ansonia, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inMechanical Movements; and I do hereby declare the following, when takenin connection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a sectional side view of mechanism illustrating the invention,with the parts in the down position; Fig. 2, the same, representing theparts as ascending, producing the transverse outward movement; Fig. 3,the same as completing the ascent, showing the return transversemovement; Figs. 4, 5, 6, and 7, modifications.

This invention relates to a mechanism for producing a vibratory movementof one part of a machine from a reciprocatingmovement of another part ofthe machine, the mechanism being adapted for various purposes, theobject being to produce a back and forward or vibratory movement of theone part during the movement of the other partin one direction only, thereturn of the said other part producing no effect upon the one part; andthe invention consists in the construction,as hereinafter described, andparticularly recited in the claim.

I first-illustrate the invention as it may be employed in abutton-setting machine, showing only so much of the machine as necessaryto the understanding of the invention.

A represents a vertical reciprocating slide; B, a lever hung to theslide upon a pivot O and so as to swing in a vertical plane toward andfrom the slide. The lever is extended above the pivot, and is providedwith a spring D, the tendency of which is to force and yieldingly holdthe lower end of the lever toward the slide, as represented in Fig. 1.At the lower end the lever is provided with the button-holder E. This,however, constitutes no part of the presentinvent-ion further than tosay that it is adapted to receive and hold the button or thebutton-fastener, as the case may be, such button or fastener beingdelivered to the setter in the usual manner.

F represents a stationary cam in rear of the lever 13, and hererepresented as projecting through an opening Gin the slide. The face ofthis cam toward the lever is constructed with a transverse depression a,and above this is a second depression 11, forming a transverseprojection 0 between them. On the side of the lever next the cam arecess (Z is formed, and which when in line with the two depressions (Lb and the projection c, as seen in Fig. 1, will produce a V-shapcdrecess between the cam and the lever, open from top to bottom. Betweenthe face of the cam and the lover a roller E is introduced, which isadapted to roll from one depression a, as seen in Fig. 1, over theprojection c, as seen in Fig. 2, and into the depression I), as seen inFig. The depression Z) is of a depth corresponding to or somewhatgreater than the diameter of the roller e, and so that when standing inthe depression l), as seen in Fig. 1., it is back of the plane of thatface of thelever. The slide and lever both receive the same verticalreciprocating movement to take them from the position seen in Fig. 1 tothat seen in Fig. 3. As the slide and lever commence their ascentfromFig. 1 the roller e on the stationary cam will be caused to ride up theincline from the recess a onto the projection c, as seen in Fig. 2. Thiswill impart to the lever B an outward swinging movement, as seen in Fig.2, the spring D yielding under such forced movement of the lever; but sosoon as the rollere passes the projection c it comes upon the oppositeincline into the depression I). The spring is now free to react and thelever returns, forcing the roller c up into the depression Z), as seenin Fig. I), where it lies free and without effect upon the lover orslide. Upon the return of the lever and slide the roller retains itsposition in the upper depression I) until the lever has reached its downposition, so as to bring its recess (Z into line with the face of thecam, as seen in Fig. 1, when the roller will descend by its own gravityinto the lower depression a, and there remain until the lever againascends. The descent of the lever and slide may continue below thisposition (seen in Fig. 1) so long as the depression (I will leave theroller c free-that is, until the upper side of the recess (Z shall cometo a bearing upon the roller; but the illustration, as in Fig.1,1nayproperlybe considered as the down position of the slide and lever.This operation of the roller between the cam and the recess in the leverwill continue at each ascent and descent of the slide and lever, and theoutward swing and the return movement of the lever will be producedwhile the slide is "moving in one direction, and on the return movementof the slide the lever will receive only the same descending movementwithout the swinging movement.

The invention which I have describedis applicable to various purposes.As another illustration, in Figs. l, 5, and 6 I show it as applied to afeed. In these illustrations A represents the vertically-reciprocatingslide, as before, and B the swinging lever. In this modification Irepresent the cam as moving with the slide instead of stationary, as inthe first illustration, and whereby the lever is hung so as to swing asbefore, but without partaking of the reciprocating movement of theslide. I11 this case the lever B is hung upon a stationary pivot H andcarries a pawl I at its lower end adapted to work into a toothed ratchetJ as usual for pawls and ratchets. In the face of the slide toward thelever the cam is formed, consisting of similar depressions a b with thecentral projection c, and the lever is constructed with substantiallythe same recess 01 as in the first illustration. In Fig. 4 the slide Ais represented in substantially the up position. As the slide descends,the roller ewill ride upward from the depression 0. onto the projectionc, and, bearing upon the face of the lever, will force the lever toswing forward until the roller 6 has passed the projection 0. Then thereaction of the spring K will force the lever rearward, the roller 8slipping into the depression I), as seen in Fig. 6, bringing the leverback to its normal position. Then as the slide returns it will produceno efi'ect upon the lever B until the recess d in thelever comes intoline with the two depressions a Z) of the cam, as seen in Fig. 4:, whenthe roller will return from the upper depression into the lowerdepression by its own gravity.

The invention is not to be understood as limited to imparting a fullvibratory movement from one direction of reciprocation, as the movementmaybe back and forward transverse to the path of the reciprocatingmovement, as seen in Fig. 7, in which, instead of a lever having adepression in its face, a slide L is arranged at right angles to thepath of the slide A, from which it will be evident that the same resultis attained, to wit: producing a full backward and forward movement ofone part transverse to the line of reciprocation of the other part andduring the movement of the said reciprocating part in one directionwithout effect upon the said transverse part during the return movemenof the said reciprocating part.

These illustrations will be sufficient to enable others to apply theinvention where similar results are desirable.

I claim- The herein-described mechanism, consisting of one part having areciprocating movement imparted thereto, a second part adapted to movelaterally toward or from the said reciprocating part, a cam in the faceof one of said parts consisting of two transverse depressions, one abovethe other, forming a transverse projection between them, the surfaces ofthe two depressions inclining to the said projection, the adjacent faceof the other part constructed with a corresponding recess, the said camhaving the one part constructed to pass said depressions in onedirection and come into line with it in the opposite direction, with aroller upon the said cam and between it and said lever, substantially asdescribed, and whereby under the movement of the said reciprocating partin one direction the said roller will be caused to roll from the lowerdepression up onto the projection, thereby imparting transverse movementto the other part, and the roller under the continued movement of thereciprocating part will escape into the upper depression to permit thereturn movement of the said other part, and so that on the return of thesaid reciprocating part the said roller will return of its own gravityfrom the upper depression into the lower without effect upon the saidother part, and substantially as specified.

In testimony whereof I have signed this specification in the presence oftwo subscrib- 10o ing witnesses.
